Atsumori, roughly 17 years old at the time of the battle of Ichi-no-Tani (1184), was killed by the Minamoto warrior Kumagai Naozane. In the Heike monogatari and many works derived from it, this is focused upon as a particularly tragic episode. Atsumori is also, like many of his Taira brethren, portrayed as a courtier and poet, not truly prepared for battle. He is said to have carried a flute into battle, evidence of his peaceful, courtly nature as well as his youth and naïveté. Kumagai also notes that none of his fellow Genji (Minamoto) warriors were cultivated to a point where they would ride into battle with a flute. Royall Tyler's analysis, preceding his translation of the play, focuses on the contrasts between Atsumori, the young, peaceful courtier and flute player, and Kumagai, the older seasoned warrior.
